rownn FARMING ArranATUs.

This invention relates to power farming apparatus. f.

h'lechanical power has been utilized Vfor ital-ming purposes in the form or tractors usually propelled by internal combustion en- `eines. The advisability ot using tractors 1s generally a n'uttter ot economics, that is, first cost and nmintenance. Object-ions to this type of power from some sources have been its high cost and the fact that the tractors have not been suitable for use in all kinds oittarm' work, or, it' suitable, as in the case of certain 'front wheel drive tractors, the implements tor use with the tractor have been special and too expensive. The goal toward which many have been striving is to provide a relatively inexpensive tractor which can beused tor all farming purposes,a tractor that can be operated by one man, and one that does not necessitate a large expenditure for special tools and implements. The present invention has been directer. toward this end.

The general object ot the invention is to provide an improved power farming apparates.

More provide specifically, the object has been to a universal implement carriage for a trent wheel drive tractor to which implementearriagije can be attached a wide variety ot simple devices capable of being used for periorming the` various functions required on a farm.

Otherand more specilic objectswill appear 'from the specification and drawings.A

An embodiment of the invention is illustrated in the drawinp's in which,

the implements being shown in raised positl e adparts shown in a different adjusted position.

F igure 9 is a small rear elevation illus-f tratinn how certain plows may be attached.

trat/ed in reissue latent No. 141,985, Novem-` lier 16. 1920. A tractor ot' this type usually has a rearwardly extending coupling` frame 1 pivoted to the mainbody of the tractor to swine; about a substantially vertical axis.

The 'trame supports a steering wheel 2 andcontrol devices 3, .thesteering wheel being larranfred to rotate a .steering pinion 4. cooperating with a rack 5 on the tractor frame 'for swinging `the coupling frame relative to the tractor lior steering purposes. Vrl`wo brackets 7 extend downwardly from the` trame to serve as attachingl means torreonnecting; the trame to a devicev to be drawn. The tractor also has a draw bar 6 which may either-be attached'to the main trame of the tractor or to the couplingl frame as illustrated in Figure 1.

The universal implement carriage provided for attachment to the coupling` frame com-- prises, in general, a frame 10 supported by a crank .ide 11 carrying ground wheels 12 and 13, a floating` ldratt frame 14. carrying an implement-attaching bar 15, and power-lift raising' mechanism 1 6 'for the draft frame.

Theifram'e 10 is oit triangular shape as ill'ustrated in Figure (Sand .comprises two side members 20 and 21 connected at their rear by a cross brace 22 and near their center by a second cross brace 23 to the latter'oitl ywhich the crank axle 11 is bolted by bolts 24. Thel traine supports a seat bar 25 carrying the. sea-*926. The front end ot' this bar is bolted to the under side of aY bracket 27er. the cross brace 23, and it extends through' a slot in a support 28 bolted to the rear cross lorace 22.`

The support 28 extends above brace 22 in one of its positions as illustrated in Figure 7, in which case, the seat is in its highest location. hut if itis desired to lower the position 01"' the operator, the support 28 may be swung around so as to extend down below the brace 22, the seat bar 25 having a `curve in it as shown in Figure 1,`to permit of these two positions.

The frame l() is attached to the coupling frame l of the tractorby means of ins 29 which extend'thro'ugh the downward y projecting brackets 7 on the couplingframe. This pin connection permits a slight movenient of the carriage frame relative Vto the' coupling frame in a longitudinal direction and also permits the frame Vtoswing about a Vsubstantialily longitudinal, horizontal axis to adjust itself to Vinequalities in the surface of the ground. j l j f l Y The crank axle llisrigidly attached to the frame in lan upright positionV and the supporting'wheels l2" and i3 are journaled on its `ends. The shapeof the crank axle and the type of supporting wheels may be varied to suit the requirements.l but the construction illustrated has been found desirable. f

One ofthe most difficult problems is'to provide mechanism to associlatewith, the

r frame to efficiently perform all thev various v functions required of an apparatus designed The for universaluse in power farming.

Virstthing is to provide a constructions,that 'u will ermit a widervariety of farmimplement attac iments to be connected to it to-pcrform the various. farming functions.` VThere enters intolths problem the questioni of height and character of. draft; For plows, the l draft must below and adjustable, while for certain i other implementsthe `draft shouldwpreferably be hirh. The carriage is frequently in aninclinec position when operating,` that is,

' i one wheel will be in a furrow, but it is neces-V saryvto, have the implements level. There must be adjustments for r'depth and; there must be Vsome provision for raisingthe implementsfrom working position. The construction must prevent wobblinr ofthe implementsflyet .it must be ,flexible enoughv to `permit adjustments in various directions.

All these; results must be accomplished by j mechanism that is relativelyisimple, mechanism thatis durable, and mechanism that can be made without involving either ahigh first` cost `or highI maintenance cost. The problem j has been solvedrin the present invention by Vthe*provision-ofa-tloating draft frame hav-Y ing various adjustments and associated mechnected` atztheirseparated rear ends byan im'- j sanismwhichwvill nowvbe described. j

llhedra-ft frame has two forwardlyfcon-` vergingside members 30 and 3l connected toeach other at their forward ends an'dlcon plement-attaching bar 15` to which they are clampedby `clam s 32. Fixedon:V the outer sides o f the mein rs 30 andBl respectively, are U-sliaped members 33 which cooperate VVwiththe eaves 34-fancl35 on thelinks 30' and j 37. The draft frame `is hung on these links which are adjustable and which may be raised in a manner which will be described in detail hereinafter. iThe locationV of the U-shaped brackets is "such, that the `frame is approximately in balance when no implements are connected `to the bar 15, thatis, it is in ball" ance about an axis extending through the eyes 34 and 35j. Preferablyit is just slightly f over balance to the rear so that the dral t device in front will be held taut. By lifting and lowering the links 36 and 37, either one 7 or both sides of the frame may be raised or lowered and adjusted. `In otherl words,the .l

frame may tilt sidewise and it `maymove up yand down, or it may ,swing about an axis through the eyes 34 and 35. It is undesirandto prevent this there areprovi'ded two arms 38 and. 39, one pivoted tothe member 30 .and the other to the member 31 andthe two converging forwardly to form a twig-uefa()-l and extend downwardly. The connectionbetween the tongue 40 and the bars is relatively' loose s o `that the tool-attachingI bar 15 may ,be tilted sidewise freely#` The'Vshape ofthe pivoted draft bars 52 and 53 that convergeV `forwardly and-are attached to the clevis 54,

thatiniturn, maybe adjustably connected `to,V the tractor draw bar 6. The forward end of j the draft frame isc'ronnected to the converg- 1 ing ends of thedraft bars by a chain 55, the length of whichmay `be-adjusted-by cha-nging the link which ,is inserted inaslot inthe i A Vpivoted catch -attajchedto the frontend of Y the draft frame. Whenjthe draft frame is 1 raised, the draft hitch is rigid as illustratedV in Figure l and the frontend of the draft i frame-is prevented from" rising. lVVhen` the draft frame is lowered, the draft hitch isLin the position shown in Figure V3,1m which posi-` f1 tion, it is flexible, permitting-a certain amount Y of relative movement between the tractor and frame. VAs `the draft frame is' raisedfrom the position of Figure 3, the ltendency 'is for I fits front end to raise firstbecause more weight 1 is behindthe axis of theeyes 34 and 35 when the implements are `attached than is infront of this-axis, consequently, 'the front end of ,the :draftframe will tend torise, but such rising action will be limited by thedraft 1 Sil able,however,.to have the frame moved sidef wise bodily when it 1s m. operating pos1t1on,"`

i This tongue is positionedin ajgroovefor slot formedby the converging ends of two bars Y 4l and 42,` which are' pivoted to the *frame Ulf ttl

hitch, which becomestaut, whereupon any further raising act-ion uponA the draftframe frame is hung, are connected to theupper endsy of links 60 and 61 that are pivoted in arms 6L L and G3 lixed to a shaft j.64 journaled in the frame of the truck, rllhis shaft has another arm G5 which is connected to a link 66, that in turn, is connected to the crank G7 of the powerlift mechanism 16 operated by power from the ground wheel 13. r1`his powerlift mechanism is thrown into operation by a movement of the lever 68. 1f, with the crank G7 inthe position shown in Figure 4, the lever 68 is moved to the right momentarily, the clutch is thrown int-o operation with the crank moving clockwise and will continue. to operate until automatically stopped in the position shown in Figure 3. If the lever G8 is actuated when the ejank is inthe position shown in Figure 3, the clutch will beset into op ration with the crank G7 moving clockwise and will continue to operate until automatically stopped in the position shown in Figure 4. A more detailed descriptionof the powerlift mechanism is contained in Patent No.v

1,565,619, Dec. 15, 1925 to which reference is made. Y

When the crank 67 of the powerlift mechanism is in the position'shown in Figure 3, the draft frame is lowered andthe connecting links assume the position shown in fulllines.

lVhen the crank G7 of the lifting mechanism isl in the position vshowin in Figure 4, the draft frame is raisedand the connecting links occupy the position shown in full lines in Figure 4 and in dotted lines in Figure 3. n

The movement of the links when the lifting mechanism operatesis as follows: y `When the crank moves in aclockwise direction from the position shown in Figure 3, the link G6 moves upwardly carrying with the arm', thereby rotating the shaft 54m a counter-clockwise direction, whichv in turn rotates arms 62 and 63 in a counter-clockwise direction and swings the links .GO and 61 upwardly carrying' with them the links 3G and" 37 attached to the draft frame, thereby lifting the frame. The .reverse action takes place when the crank 67 moves from the position of Figure 4 to that of Figure 3. l l

The adjusting mechanism is duplicated on each side ofthe machine and for thesake of simplicity, only one side will be described. it includes a link 70 pivoted to the joint between links 36 and 60 and connected to the forward end of a bent lever 71 pivoted at a point 72 to the frame and having a latch 73 cooperatingvwith the toothed segment 7 4 attached to the frame. e

When theparts are in the position shown in, Figures 1 and 4, that is, when the draft frame is raised, movements of the adjusting lever 71 will have very little, if any, effect upon changing the height of the frame. difference in the position of the links is illustrated in dotted lines in Figure 1 where the adjusting lever is shown in dotted lines at one of its extreme positions and in full linesI in its other extreme position. ltwill be noted that the link 66 is at the top of the aro so that the effect in raising or lowering the link and v-the frame connectedyto 1t is negligible.

@n the other hand, if the adjusting lever 71r is moved when the parts are in the position ,shown in Figure 3, the link 6G will be moved a very substantial amount vertically. By moving the lever from its full line position shown in Figure 3 to the dotted line position, thelinks are moved from their full linefto their dotted line position and the frame raised to the full height of its adjustment. s

rThere is annadju-sting mechanism of this The kind on both sides of the carriage so that .i

either side of the frame may be moved independently of the other. Y'

in important feature of the construction of the adjusting mechanism is that the frame is lifted. by the power-lift mechanism to substantially lthe same height above the ground and to a level position from all positions to which it may have been lowered or adjusted. This action results from the fact that all the adjustments of the links 3G and 37, when the;7 are in raised position asillustrated lin Figures 1 and 4, leave the link in substantiallyy the same position as far as height above the ground is concerned. For example, assume Athat the mechanism is adjusted so Vthat when thedraft frame is lowered, it is in its very lowest position. lV ,henA it is raised, thelinks and 37 will assume one position lf, on the other hand, the mechanism is adjustedso that when the draft frame is lowered, it is in its highest operative lowered position, the link @6 will be in another position when the frame 1s raised, but whether `the link be inthe first raised position, or the second raised position, it will be at substantially the same height. above the ground, consequently, the draft.

framewill be atsubstantially the same height above the ground. This also result-s in the draft frame being level when raised because, even though one side is lowered more than the other when operating, nevertheless, when les,

llo

Vtwo of its edges are in substantially vertical alignment. The bar is made longer, than the width of the carriage so that im lements ma be attached out near its ends or'work suci as plowing in orchardsand the like.

The position of the attaching bar, that is,

with two otits edges in vertical alignment,

permits the'use of clamp brackets such as the structure-or similar'devices depending u en twol points of Contact for support. j hej` brackets 32 are made wide enough to prevent any twisting of the implement.

The general operation of the mechanism is as followsz-v Y f With the parts in `the position shown' in yFigure 1, the operator is lseated onthe seat' 26 wherehe *is ina convenient position to steer'the tractor, to manipulate its controls, Y I without damagingthem` by havingportionsV to adjust the levers 71 and to set the lifting mechanism into operation. In this position,

the draft frame is raised and the implements `are clear of the ground. i The `tract-or may be Y driven over Y work.

Y be adjusted to suitthe requirementsand, if the truck is'tilted slightly, as it would bein the' event that one wheel were running in a furrow, the operator can Vlevel the implements by adjusting the levers 71.`

When the operator desires ing. ThisV insures that` the implements will always be clear oit the ground when the frame is raised.` v It also avoidsthe necessity 1 for readjustment of thelevers 71 when the frame is raised; l"The operator 'can set'these levers for a certain`l depth adjustment and-aftersition and always raised to thefsame levelV position abovethe ground.

As the frame is lowered, the parts move to the position illustiated in Figure 3. The shaft 63 rotates in a` counter-clockwise direction carrying with it the arm 123 and the link 122. Movementin thisV direction is resisted by the tension of spring 1Q() which thereby resiliently opposes a downward movement of the draft frame. lt prevents 'the frame from dropping suddenly with such force vas to break the tools attached to it. The spring also serves to assistin raising the frame-when the power-lift mechanism is opera-ted for that purpose.

With a device of this kind, a farmer may use one power unit for all farming purposes without having to' buy separate complicated implements for every class of work to be done. After having this power unit, he need only procure simple inexpensive attachments for the different kinds of Work. The transition from horse-drawn implements to tractor drawnV may he gradual, that is, the device is constructed so that in case the "farmer wishes to use an old drag-behind plow, for example,

he may do so by simplyhitching it to the har 15, the same as with a four-wheel tractor.y

' It is to be understood that variations may be made Without departing from the spirit and scope of the invention as defined by the claims.
